In one aspect, the fluid transfer assembly includes a fluid container having an opening in a bottom, a coupling device attached to the fluid container at the opening, and a filling device. The coupling device may include a valve biasing the coupling device in a closed fluid-tight position via magnetic attraction of opposing first and second components, each of the opposing first and second components including a magnetic material. The filling device may include a rigid member with a perimeter smaller than a perimeter of the fluid container opening, the rigid member including a passage along a longitudinal axis and one or more apertures through a sidewall in fluid communication with the passage, such that the coupling device is transitioned from the closed fluid-tight position to an open position by pressing the rigid member against one of the opposing first and second components, thereby placing the apertures in fluid communication with an interior of the fluid container.

PRIORITY

This application claims priority to U.S. Provisional Patent Application No. 61/054,686, filed May 20, 2008, entitled “Pressure Valve and Assembly,” and to U.S. Provisional Patent Application No. 61/154,726, filed Feb. 23, 2009, entitled “Beverage Dispenser,” each of which is incorporated by reference in its entirety into this application.

BACKGROUND

Various types of containers are designed to hold beverages, from cans and bottles, to cardboard boxes and wooden casks. Liquid may be stored in large containers and transferred to relatively smaller containers for consumption via a spout, hose, facet, tap, or fountain. Such transfer methods fill a serving container from the top of the serving container, or through the surface of the filled liquid in the serving container. However, filling a serving container from the top may increase foam of carbonated beverages. To reduce the foam, a user generally pours out the excess from the serving container, thereby wasting liquid. Alternatively, a user may wait for the foam to settle, which requires extra serving time and attention.

Accordingly, top filling methods generally require a server to perform a number of actions, including properly positioning the serving container, starting the flow of liquid, stopping the flow of liquid, and removing the serving container, each action requiring coordination and usually physical contact with the serving container during the filling process. Moreover, transfer devices for top filling methods often take a large amount of space on a counter or serving area, and require attention to operate and control.

DETAILED DESCRIPTION

In the following description of exemplary embodiments, reference is made to the accompanying drawings that form a part hereof, and in which it is shown by way of illustration specific embodiments in which the invention can be practiced. It is to be understood that other embodiments can be used and structural changes can be made without departing from the scope of the embodiments of this invention. As used herein, the terms “couple,” “connect,” and “attach” are interchangeable and include various forms of connecting one part to another either directly or indirectly. Also, it should be appreciated that one or more structural features described in one embodiment could be implemented in a different embodiment, even if not specifically mentioned as being a feature thereof.

In the following description, numerous specific details are set forth, such as examples of specific containers and liquids, in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. For example, the description is discussed generally in terms of devices used with a keg for dispensing beer into a glass or pitcher; however, the device may be used with other beverages, such as sodas, and other beverage containers, just as glasses or mugs, and storage containers other than kegs. Disposable cups are also envisioned as an alternative container, which may be used for beverages at parks, concerts, or other venues where glass is not permitted. Alternatively, the device is not so limited in the type of liquid stored and transferred. For instance, embodiments of the device may be used in transferring various fluids between two containers according to the below description, such as, for example, oil. Gaseous substances may also be transferred using embodiments of the assembly. The specific details may be varied and still be within the spirit and scope of the invention.

The fluid transfer assemblies and methods of fluid transfer described herein are believed to provide advantages in commercial applications, including the selling/serving of carbonated beverages such as beer more efficiently and effectively, providing a novel means for reaching target markets (e.g., use of a message such as a logo/slogan on a viewable and perhaps removable part of a mug or pitcher containing the novel coupling device described herein), etc. The fluid transfer assemblies and methods of fluid transfer described herein are also believed to provide advantages as a consumer product which can be utilized in a local setting, including the filling of containers with carbonated beverages and the customization of portions of the assembly. For example, it is contemplated herein that a family or group could host a party or special event using the fluid transfer assemblies and methods of fluid transfer described herein, customizing a viewable portion of the container to include a message, including a picture and/or text depicting the theme of the party (e.g., “50th birthday,” “Family Annual BBQ,” etc.). Further examples include sports team representations, wedding day graphics, amusing pictures, jokes, etc. Such viewable portions of the container or assembly could be removable as discussed below (e.g., a magnetic cap) to provide each person attending the party or special event a souvenir to take home.

In one embodiment, a method for filling a container through its bottom is provided. Filling a container through the bottom via use of the devices and methods described herein is advantageous, for example, in controlling the amount of foam created and significantly reducing the “head” on a carbonated beverage, such as soda or beer, relative to conventional methods. Moreover, by filling through the bottom of a container, the foam is pushed up and over the rim of the container, thereby reducing the amount of wasted beverage. A server may also benefit by not having to hold and tilt a glass or pitcher while pouring to remove the foam. Further, the number of taps may be reduced as more than one type of beverage may be poured from the same system. Alternative embodiments include a dispensing system assembly and device for filling a container through the bottom. Other embodiments of the system include liquid evacuation for cleaning between uses, as well as rapid drain attachments to remove a beverage after filling the container.

FIG. 1 illustrates a representative container connected to a beverage dispenser according to embodiments of the design for filling a container through its bottom. Referring to FIG. 1, a dispenser 100 is illustrated including a container 102 coupled and ready to be filled. The dispenser 100 may be used to dispense beverages, including carbonated beverages such as soda, beer, etc. The container 102 may be any container for receiving the liquid, including for example a pint glass, mug, disposable glass, or pitcher. The container 102 may couple to the dispenser 100 at or near the bottom 104 of the container 102. Therefore, the container 102 is filled below a surface of the filling beverage during the dispensing process.

In one embodiment, the container 102 includes a container connection device 106 that is designed to couple to a dispenser connection device 108. The dispenser 100 may be coupled to a fluid source, such as a keg or carbonation and soda lines. The container connection device 106 may include a valve that opens when coupled to the dispenser connection device 108 and permits fluid flow therethrough. The container connection device 106 may then close when the container 102 is removed from the dispenser 100, thereby preventing leaks from the container 102. The dispenser 100 includes a housing 110 shaped to properly align the container connection device 106 with the dispenser connection device 108. The dispenser 100 may also include a basin 112 to catch any potential spilled liquid. The basin 112 may include various shapes, such as a bowl, raised lip, or recessed area. The basin 112 may include a drain 114 for easy disposal of caught liquid.

According to one aspect of the invention, during use, the container 102 is coupled to the dispenser 100. When the attachment is made, the container connection device 106 and the dispenser connection device 108 engage to create a fluid path between the container and a fluid source, such that the container 102 is filled from a bottom portion thereof. A user may overflow the container to remove any extra foam that may be created at the top of the container during the filling process. Alternatively, some fluid may spill during the removal or filling process. The basin 112 is designed to catch the overflow liquid, which may be removed through drain 114 to facilitate cleaning. When the container 102 is removed from the dispenser 100, the container connection device 106 may be disengaged from the dispenser connection device 108 to seal the container 102 from leaking.

In one embodiment, the dispenser 100 may be a separate device removed from the liquid source, but coupled by a hose or tube or other liquid transporting device. The dispenser 100 may be incorporated into, or coupled to, an immobile surface, such as a countertop, or may be an independently movable platform to be arranged at the convenience of the user. The dispenser 100 may also be in various shapes, and include additional features, such as the housing 110, basin 112, or drain 114. The dispenser 100 may alternatively include audio or visual devices. For example, the dispenser 100 may include information, logos, or designs identifying the contents associated with a specific dispenser. In one embodiment, the dispenser 100 may include lights that may be colored, or flash, or speakers that turn on when a container 102 is connected to the dispenser.

FIG. 2 illustrates a representative progression of an exemplary embodiment of a container 202 from a closed, liquid-holding state to an open, liquid-filling state, when the container 202 is coupled to a dispenser connection device 204. In one embodiment, the container connection device includes a valve, such as, for example, a cap 206, which is normally closed. The cap 206 is coupled to the bottom of the container 202 and may include a liquid-tight seal to prevent fluid flow out the bottom of the container.

In one embodiment, the cap 206 may be used as an advertising space, visible to a consumer while they are consuming their beverage. For example, in such an embodiment the cap 206 may include logos, images, etc. to promote a commercial enterprise or relay other information to the consumer. In one embodiment, the cap 206 itself, or a removable portion thereof, includes a magnetic material and commercial information, thereby serving to promote a company or product. For example, the magnet could have a company name and/or logo and could be taken home by a consumer as a souvenir for use on a refrigerator or other metal structure such that the company name and/or logo would be prominently displayed.

While coupled to the container 202, the dispenser connection device 204 may include a device for opening the cap 206 and permitting fluid flow between the dispenser connection device 204 and the container 202. The dispenser connection device 204 may couple to a liquid storage container, such as a keg, barrel, or other container. The dispenser connection device 204 may include a conduit to transfer the liquid from the storage container (not shown) to a serving or other container 202. The conduit may be generally flexible for guiding contents from the storage location to the dispensing location without kinking or impeding the fluid flow path.

FIG. 2A illustrates the container 202 in a closed configuration, capable of holding a fluid. The container 202 may be any beverage holding vessel, including a cup, pitcher, pint, mug, or the like, or any non-solid holding vessel. The container 202 includes a bottom 208 that may be used to support the container 202, and side walls to hold a fluid. The container 202 also includes a top opening for dispensing the contained fluid, such as for pouring or drinking. The bottom 208 has a bottom opening separate from the top opening, to permit fluid flow during filling. The bottom opening may be covered by a valve that creates a fluid tight seal when the container is not being filled. In one embodiment, the valve includes a cap 206 that is normally biased close to create a fluid tight seal. The cap 206 may include a magnetic material that is attracted to a complementary magnetic material of a ring 210 on bottom 208 of container 202. Ring 210 may generally encircle an outer edge of the hole, while the cap 206 has a shape and diameter that covers the hole and may overlap at least a portion of the ring.

FIG. 2B illustrates the container 202 in contact with a dispenser connection device 204, but before the valve of the container is opened. The dispenser connection device 204 is aligned with the bottom opening of the container 202. The cap 206 of the container 202 is biased closed by, for example, a magnetic attraction to the ring 210. The dispenser connection device 204 includes a nozzle 212 with holes 214 to permit fluid flow during filling. The nozzle 212 is dimensioned to fit inside the bottom opening of the container 202. The nozzle 212 pushes against the cap 206 and opens the valve of the container 202 to permit fluid flow for filling.

FIG. 2C illustrates the container 202 coupled to the dispenser connection device 204 when the valve of the container is open for filling. Nozzle 212 pushes against cap 206 as the nozzle enters the container 202 and exposes apertures 214. In one embodiment, once the container 202 and the dispenser connection device 204 are coupled, fluid is permitted to flow by opening a valve on the dispenser connection device 204. In an alternate embodiment, fluid automatically flows when the apertures are exposed. For example, the liquid in the dispenser connection device 204 may be kept under pressure. When not in use, the apertures 214 may be covered by a platform 216. When the container 202 is coupled to the beverage dispenser, the nozzle 212 may push against the cap 206 opening the valve of the container, while the bottom 208 of the container pushes against the platform 216, exposing the apertures 214. Once the apertures 214 are exposed, liquid may flow from the dispenser connection device 204 into the container 202 through the apertures 214.

When the nozzle 212 is removed from the bottom of the container 202, the valve of the container closes and seals the container such that liquid is held therein. When the valve is sealed, the container 202 may be used to hold the newly added liquid. In one embodiment, the cap 206 is continually attracted to the ring 210. When the influence of the nozzle 212 is removed, the cap 206 rests in a closed position against the ring 210, sealing the container 202. The fluid from the dispenser connection device 204 may be contained by closing a valve on the beverage dispenser. In one embodiment, as the cap 206 seals the container 202, the platform 216 seals the apertures 214. Therefore, fluid is prevented from freely flowing out of the dispenser connection device 204 when a container 202 is not attached.

FIGS. 3-5 illustrate representative embodiments of a container connection device coupled at the bottom of a container. As described above, the container connection device may be designed to couple to a dispenser connection device. The container connection device may include a valve that opens when coupled to a dispenser connection device that permits fluid flow therethrough. The container connection device may then close when the container is removed from the dispenser, preventing any leaks from the container.

FIG. 3 illustrates a representative embodiment of a container bottom 300 from a top view, including a hole 302, cap 304, and ring 306. Hole 302 may permit fluid flow during filling from the bottom of the container. Ring 306 may surround a circumferential edge of the hole 302. Cap 304 may cover hole 302 and at least a portion of ring 306, and may overhang ring 306. Cap 304 and ring 306 may include magnetic material, such as a ferrous metal. The magnetic properties attract cap 304 to ring 306, sealing hole 302. Cap 304 may be coupled to the container bottom 300 so that it may be easily removed, such as by the magnetic attraction to the ring 306. Ring 306 may be more permanently coupled to container bottom 300, such as by adhesive, screwing, or integrally molded into the container bottom. The cap 304 and/or ring 306 may include a sealing device, such as an o-ring or gasket, to better ensure a fluid tight seal around hole 302. Alternatively, the container bottom 300 may include a sealing material, such as rubber, between the cap 304 and ring 306 to create a fluid tight seal.

The cap 304 may be of various shapes. For example, in one embodiment, the cap may be a flat, generally circular disk that fits inside the container bottom 300. Alternatively, the cap 304 may include a contoured surface to mate with the hole 302 to properly align the cap 304 to the hole 302 or to create a better seal for the hole. In one embodiment, the cap 304 may be contoured to mate with the dispenser connection device. For example, the cap 304 may include a recessed contour on an underside to receive a portion of the dispenser connection device and hold the cap 304 in a desired location during the filling process.

FIGS. 4A-B illustrate a representative embodiment of a container connection device 400 including an upper section and a lower section capable of connecting together at a bottom of a container. FIG. 4A illustrates a cut-away view of the representative embodiment of the upper section and lower section in an unassembled state, while FIG. 4B illustrates a cut-away view of the representative embodiment in an assemble state with the upper section and lower section attached together and to the container around the bottom opening. The attachable sections of the container connection device 400 permit removal of the container connection device for cleaning or use with other containers. The upper and lower sections 402, 404 may be threaded to engage one another through an opening 408 in the bottom of the container 406. The sections may alternatively be joined by other means, such as gluing or bonding. The container connection device may alternatively be integrated directly into the container bottom.

In one embodiment, an upper section 402 may couple to a lower section to create the container connection device 400. A lower section 404 may include a generally cylindrical shaft 410 that has a diameter smaller than opening 408 in the bottom of a container 406. The diameter of the opening 408 and the shaft 410 may be generally the same size to create a snug fit to assist in leak reduction and proper alignment between the container connection device 400 and the container 406. The shaft 410 may alternatively be relatively smaller than opening 408 in the container 406 to permit alternatively sized container connection devices to be coupled to the container bottom. The inner diameter of the shaft 410 may be sized and shaped to accommodate the dispenser connection device as explained further below. The outside of the shaft 410 may include threads 412 to engage the upper section 402. The upper section 402 may be generally cylindrical in shape with an inner opening 414 including threads 416 to engage the threads 412 of the lower section 404.

The lower section 404 may also include a flange 418 at the base of shaft 410. The flange 418 may have an outer diameter greater than the opening 408 to provide a surface to engage the container 406 bottom. The flange 418 may include a seal member 420, such as an o-ring or gasket. The seal 420 may press against the bottom side of the container 406 when the upper section 402 engages the lower section 404 to create a fluid tight seal. The upper section 402 may also contain a seal member 422 on a bottom side to press against a top surface of the container 406. Therefore, a portion of the container 406 may be sandwiched between seal members on the upper section 402 and the lower section 404 of the container connection device.

The container connection device 400 includes a cap 430 including a magnetic material and shape configured to mate with the upper section 402. In one embodiment, the upper section 402 includes a rim 428 with an inner surface that mates with an outer surface of the cap 430. Of course, in alternate embodiments the rim could have an outer surface to mate with an inner surface of the cap. The rim 428 may be a generally cylindrical rim with an inclined inner edge to direct the cap 430 to a central position over the inner opening 414 of the upper section 402. The inclined edge permits a space to form between the upper section 402 and the cap 430, when the dispenser connection device presses the cap away from the upper section. In one embodiment, the upper section 402 includes a magnet 424 to attract magnet 432 in the cap 430 to bias the cap in a closed position. The two magnets 424 and 432 may be rings or discrete magnetic pieces coupled to the respective sections. The magnets may be adhered, bonded, integrally formed, molded, or otherwise attached to the respective sections to attract the cap to the upper section. Alternatively, the material used for the upper section and/or the cap may be magnetic. In one embodiment, the cap 430 may include a recess 434 to mate with the dispenser connection device (not shown). The recess 434 may receive a portion of the dispenser connection device that opens the valve by pushing upward on the cap 430 and providing a space between the cap 430 and upper section 402. When the dispenser connection device is removed, the magnetic attraction between the cap and upper section closes the valve, and the rim of the upper section ensures proper alignment. The upper section and/or the cap may include a seal, such as an o-ring or gasket, to further prevent leaks when the valve is closed.

In one embodiment, the container connection device 400 may include one or more magnets. As described above, the upper section 402 may include a magnet to attract a cap 430 to act as a valve for the container connection device 400. In one embodiment, the lower section 404 may include a magnet 426 to couple the container connection device 400 to the dispenser connection device (not shown). The magnet 426 may be glued, adhered, bonded, integrally molded, or otherwise attached to the lower section 404, for example in the flange 418. The magnet 426 may attract another magnet or magnetic material included in a base or section of the dispenser connection device to stabilize the container during filling. The container connection device 400 may also include one or more seals to provide a fluid tight connection between the container connection device and the dispenser connection device. For example, lower section 404 may include a seal 436 to couple to a dispenser connection device. Upper section 402 may include seal 438 and/or cap 430 may include seal 440 to provide a fluid tight connection between the cap 430 and the upper section 402 when the container connection device 400 is in a closed position. Seals may be any sealing device known to those with skill in the art, such as o-rings or gaskets.

FIGS. 5A-B illustrate a representative embodiment of a container connection device capable of connecting to a bottom of a container according to aspects of the design. FIG. 5A is the container connection device in a closed, fluid tight position, while FIG. 5B is the same container connection device illustrated in an open position. When the valve is closed, a liquid tight seal is created to prevent leakage while the container is filled. When the valve is open, liquid may be transferred to the container from another source. The upper section 502 may be joined with the lower section 504 to permit the container connection device 500 to easily couple/decouple from a container. The upper section 502 may be modified so that the cap 530 is not freely disassociated from the upper section 502, as shown in FIG. 4B and described above.

In one embodiment, the upper section 502 may include a generally cylindrical rim 528 that circumferentially surrounds a cap 530. The cap 530 is permitted to translate up and down a longitudinal axis of the rim, but is prevented from being fully decoupled from the upper section 502. For example, the cap 530 may be a generally cylindrical button with a flange circumferentially around a central portion. The flange may rest within an indention within an inner surface of the upper section 502. The height of the indention is larger than the height of the flange so that the cap may translate within a distance defined between where the flange contacts the two subscribing surfaces of the indention. In one embodiment, the upper section 502 further includes apertures 536 that create a fluid flow path when the cap 530 is in an open position. For example, when the cap 530 is in an up or open position, a path is created between the shaft of the lower section 504 and the apertures 536 of the upper section 502. When the cap 530 is in a down or closed position, the path is sealed. The cap 530, upper section 502, and/or lower section 504 may include seals to prevent fluid leaks when the cap is in a closed position. The cap 530, upper section 502, and/or lower section 504 may include magnets to bias the cap 530 in a closed position.

FIGS. 6-9 illustrate representative embodiments of a dispenser connection device. As described above, the dispenser connection device may be designed to couple to a container connection device. The dispenser connection device may connect to a fluid source, such as a keg or soda fountain syrup and carbonation containers. The dispenser connection device may include additional features, as discussed in FIG. 1, above, such as for example, a base, basin, drain, advertisement area, lights, sounds, etc. Different embodiments of the container connection device and the dispenser connection device may be modified to include features of the different embodiments. Representative embodiments of the dispenser connection device are described below in terms of corresponding to representative container connection devices, but these devices may be mixed or altered as apparent to one skilled in the art.

FIG. 6 illustrates a representative dispenser connection device 600 according to embodiments of the invention that may be coupled to a container connection device, such as the one illustrated in FIGS. 4A-B. The dispenser connection device 600 includes a rigid member or nozzle 602 including a passage along a longitudinal axis and one or more apertures 604 through a sidewall of the rigid member or nozzle 602. The passage of the rigid member or nozzle is in fluid communication with a fluid source. The nozzle 602 is designed to open a container connection device 400 by pushing against a valve member thereof such as cap 430. The top of the nozzle 602 may be contoured or shaped to mate with a recess 434 of the cap 430 so the cap is held by the nozzle. The dispenser connection device 600 may include a magnet or magnetic material to secure the container connection device 400. For example, the dispenser connection device 600 may include a platform 606 including a magnetic ring 608 that couples to the magnet 426 of the lower section 404 of container connection device 400. The dispenser connection device 600 may also include a seal 610 to create a fluid tight connection between the dispenser connection device 600 and the container connection device 400. Collar 612 may be coupled between platform 606 and nozzle 602 to allow the platform to translate along a longitudinal axis of the nozzle 602.

FIGS. 7A-B illustrates a representative dispenser connection device 700 according to embodiments of the invention that may be coupled to a container connection device, such as the one illustrated in FIGS. 4A-B. FIG. 7A illustrates the dispenser connection device 700 in a closed position, while 7B illustrates the dispenser connection device 700 in an open position. Similar to FIG. 6, the dispenser connection device 700 may include a nozzle 702 with an aperture 704 to create a fluid path between the fluid source and dispenser device to the container. The dispenser connection device may also include a platform 706 including a seal 708 to prevent fluid leaks between the dispenser connection device 700 and the container connection device.

In one embodiment, the dispenser connection device may include a collar 710. Collar 710 may be used to retain platform 706 to the dispenser connection device 700. Additionally, collar 710 may be used to cover nozzle 702 when the dispenser is not in use, thereby potentially reducing leaks or reducing contamination or debris from entering the dispenser. The platform 706 may also include a rim 712 that may be used to seal nozzle 702 when the dispenser is not in use. Rim 712 may include an angled exterior circumferential wall so that a top edge is at a reduced diameter than the lower edge. The reduced top diameter may assist in properly aligning the dispenser connection device with the container connection device.

FIG. 8 illustrates a representative dispenser connection device 850 according to embodiments of the invention that may be coupled to a container connection device, such as the one illustrated in FIG. 3. The dispenser connection device 850 may mate with container bottom 300 to seal the connection between the fluid dispenser and container during filling. The dispenser connection device 850 may be coupled to a countertop or other serving platform (not shown). The dispenser connection device 850 may be coupled to a liquid storage container, a conduit to the liquid storage container, or the like.

In one embodiment, the dispenser connection device 850 may include a nozzle 852. Nozzle 852 may be a generally cylindrical shaped spout dimensioned to fit within hole 302. Nozzle 852 may be used to push against cap 304 to break its seal with ring 306. Nozzle 852 may include one or more apertures 854 that permits liquid to flow through and dispense into a container (not shown). The beverage dispenser may include a switch to permit fluid flow once a container is coupled to the dispenser connection device. Nozzle 852 may include a disc 862 along its top edge. Disc 862 may be used to provide advertising space, or may be used to identify the beverage coupled to the beverage dispenser. For example, the disc 862 may replace the existing beer tap used at many facilities today to indicate the types of beverages and may have other nostalgic possibilities, such as give away prizes when a brand is retired.

In one embodiment, dispenser connection device 850 may include platform 856 to assist in properly aligning the container with the dispenser. Platform 856 may be shaped to center and couple the container to nozzle 852. As an example, an outer edge of platform 856 may be generally cylindrical in shape to conform to an inner surface of a bottom rim on a container. The outer edge of platform 856 may be slightly tapered to guide the bottom rim of a container into place and properly align the container with nozzle 852. Alternatively, platform may include an upper rim (not shown) that an outer edge of a container may fit into. The upper rim may be stepped to properly align various sized containers with nozzle 852.

In one embodiment, to prevent leaks from the fluid dispenser when it is not coupled to a container, apertures 854 may be closed by platform 856. Platform 856 may be used to seal the apertures 854 when not in use. In one embodiment, platform 856 circumferentially surrounds apertures 854, when in a closed position. The platform 856 may slide axially on nozzle 852 permitting the platform 856 to expose apertures 854 during filling. During use, the container bottom 300 may push on platform 856, while permitting nozzle 852 to enter through hole 302, and therefore exposing apertures 854. Platform 856 may return to a closed position after filling. Platform 856 may move under a biasing force, such as a spring. Alternatively, platform 856 may return to a closed position under the influence of magnetic attraction between the platform and container, as the container is raised to remove it from the nozzle. The platform 856 and or nozzle 852 may include a friction connection, including a detent and flange, to secure the platform in a closed position with respect to the nozzle. This connection may be overcome, and thereby open the flow path of the nozzle, by the downward force of the container on the platform. In one embodiment, the described sealing platform may be used as the valve to initiate flow between the beverage dispenser and the container, thereby permitting fluid flow as soon as the apertures 854 of nozzle 852 are exposed.

The dispenser connection device may include a magnet or magnetic material to attract a corresponding magnet or magnetic material within the container connection device. For example, platform 856 may include a ring 864 that includes a magnetic material that may be used to secure the container to the platform 856 during filling. The ring 864 of the platform 856 may be used to attract ring 306 on the bottom of container 300. In one embodiment, disc 862 may include a magnetic material to hold cap 304 of container connection device when the container is placed on the nozzle 852, and in an open position.

Platform 856 and/or nozzle 852 may include one or more seals for a fluid tight connection between nozzle and platform and container. For example, nozzle may include a seal 858 to seal an upper edge of apertures 854, while platform 856 may include seal 860 to seal the lower edge of apertures 854, while in a closed position. Platform 856 may include a seal 866 on an upper surface to create a seal between container and platform, when in an open position. Seals may include a rubber o-ring or other gasket material for maintaining a fluid tight seal.

Platform 856 and/or nozzle 852 may be shaped to prevent platform 856 from sliding off the end of nozzle 852. For example, an upper edge of platform 856 may have a larger inside diameter that rests against a top of nozzle 852, such as for example at seal 858. The top of nozzle 852 may have a greater outside diameter to match the larger inside diameter of platform 856. The greater outside diameter of nozzle 852 may prevent the platform 856 from sliding off the upper edge of nozzle. The seal 858 may be used as the greater outside diameter of nozzle 852 to retain the platform 856 to the nozzle 852, while creating a seal when nozzle and platform are in a closed position. This embodiment permits easy installation, as the platform 856 may slide over the top of nozzle 852 for installation, before seal 858 is added.

FIG. 9 illustrates a representative dispenser connection device 900 according to embodiments of the invention that may be coupled to a container connection device. FIG. 9A illustrates the dispenser connection device 900 in a closed position, and FIG. 9B illustrates the dispenser connection device 900 in an open position. Dispenser connection device 900 may include a nozzle 902 for filling a container through a bottom thereof. Nozzle 902 may include apertures 908 to create a fluid flow path between the beverage dispenser and the container. Dispenser connection device 900 includes a nozzle 902 and platform 904 surrounding the nozzle, the platform including an opening 912 through which the nozzle is permitted to translate. The platform is attached directly to a collar 906, which is shown in FIGS. 9A-B as a flexible member, which covers apertures 908 of the nozzle in a dispenser connection device closed position, and which uncovers apertures 908 in a dispenser connection device open position.

Collar 906, in addition to being made of a flexible material to permit translation of the platform 904 with respect to the nozzle 902, may be formed of a liquid-tight material, such as a rubber or plastic, in order to prevent leaks from the nozzle 902. In a dispenser connection device closed position, the platform 904 opening is positioned generally coincident with the end surface of the nozzle. In a dispenser connection device open position, the collar flexes outward to translate the platform 904 with respect to the nozzle 902, along a longitudinal axis of the nozzle 902, such that the nozzle 902 moves through the opening 912 of the platform 904.

Collar 906 may be used in place of or in addition to seals, as described in FIG. 6. Alternatively, collar 906 may cover at least a portion of apertures 908 and prevent fluid flow when not in use. Collar 906 may be coupled between dispenser connection device 900 and platform 904 by various means. In one embodiment, the dispenser connection device 900 and the platform 904 include indentions around a lip. In such an embodiment the collar 906 correspondingly includes a protrusion dimensioned to fit within the indention and over the corresponding lip of the dispenser connection device 900 and the platform 904. The lip and indention may be used to frictionally hold the collar 906 tight against the platform 904 and dispenser connection device 900, creating a fluid tight seal. Alternatively, or in addition, adhesives may be used to couple the collar 906 to the platform 904.

The platform 904 may include a rim 910 that properly positions the container relative to the nozzle 902. The rim 910 may be a fork style coupler, including one or more prongs, or may be a solid rim, which may include a stepped bottom to accommodate various sized containers, or combinations thereof. Other embodiments, as described herein or known to one skilled in the art, may alternatively be used to position or hold the container. A seal 914 may be included on an upper surface of the base of the platform 904 to create a seal with the container. Seal 914 may circumferentially surround opening 912.

Dispenser connection device 900 may include a magnet or magnet material to couple to a container connection device. For example, platform 904 may also include a ring 916 incorporating or formed from a magnetic or ferrous material to secure the container connection device to the platform during filling. In one embodiment, a top of the nozzle 902 includes disc 918 that may be used to hold cap of the container connection device (not shown) during filling. The disc 918 may include a magnet or magnetic material to attract the cap and/or may be contoured to mate with a corresponding contour of the cap. In one embodiment, the disc 918 may include information, such as, for example, the type or brand of the beverage served from the dispenser, advertising materials. etc.

FIGS. 10-11 illustrate representative embodiments of a container connection device coupled to a dispenser connection device. When the attachment is made, the container connection device and the dispenser connection device engage to create a fluid path between the container and a fluid source. The container may then be filled from a bottom portion thereof. When the container is removed from the dispenser, the container connection device is disengaged from the dispenser connection device and seals the container from leaking.

FIG. 10 illustrates the container connection device of FIGS. 4A-B coupled to the dispenser connection device of FIG. 6 in an open position for fluid flow between a fluid source and a container. When connected, the nozzle 602 pushes against cap 430 to overcome the magnetic attraction between the upper section magnet 424 and the cap magnet 432 to expose the aperture 604 to the interior of the container 406. The container 406 is also stabilized during this process by the magnet 608 in the platform 606 as it attracts the magnet 426 in the lower section 404 of the container connection device. As shown, the nozzle 602 head is shaped to compliment the recess 434 of the cap 430 to maintain the cap in proper alignment during the filling process.

FIG. 11 illustrates the container connection device 500 of FIGS. 5A-B coupled to dispenser connection device 1100 in an open position for fluid flow between a fluid source and the container. When connected, the nozzle 1102 pushes against cap 530 to overcome the closed bias between the upper section 502 and the cap 530, thereby uncovering the apertures 536 of the rim 528. In this embodiment, the cap may be biased closed by a magnetic attract, spring, or other biasing force suitable for the device.

FIG. 12 is an exploded view of a representative dispensing system according to embodiments of the invention, including a container with a container connection device and a dispenser with a dispenser connection device, each including various features described herein. A person skilled in the art will be able to combine these and other features described herein into different embodiments, all of which are within the scope of the invention. The system 1200 includes a container with container connection device 1202, as well as a dispenser with dispenser connection device 1204.

In one embodiment, a container 1206 includes a container connection device 1202. The container connection device 1202 includes a cap 1208, cap housing magnets 1210, seal 1212, rim 1214, rim housing magnets 1216, seal 1218, bottom section 1222, and bottom housing magnets 1220. The magnets 1210, 1216, 1220 may be one or more magnetic pieces that fit within various indentions of the container connection device, solid magnetic rings, or material incorporated into the respective components of the container connection device. Seals 1212, 1218 may be any sealing device, such as an o-ring or rubber gasket.

In one embodiment, cap housing magnets 1210 comprise five neodymium magnets 1210 equally spaced around a circumference of the cap 1208 and held in place by seal 1212. Seal 1212 may be a rubber gasket generally disc-shaped to create a seal at the cap in a closed position. Rim 1214 includes apertures to permit fluid flow when the cap is in an open position, and includes rim housing magnets 1216, comprising five neodymium magnets corresponding to the five cap housing magnets, together operating to bias the cap 1208 in a closed position. Seal 1218 seals the rim 1214 to the container 1206. The bottom section 1222 couples to the rim 1214 and may include neodymium magnets 1220 to attract the dispenser 1204.

In the embodiment of FIG. 12, the dispenser includes a dispenser connection device 1204, including a first seal 1224 for a filler valve 1226, a filler valve magnet 1228, a nozzle 1230, a collar 1232 between the filler valve 1226 and nozzle 1230, and a second seal 1231. The first and second seals 1224 and 1231 may be an o-ring, gasket, or other device to create a liquid tight seal between the dispenser connection device 1204 and the container connection device 1202.

In one embodiment, nozzle 1230 may be a shaft that enters through the container connection device 1202 to push against cap 1208 and create a fluid pathway between the dispenser and the container. The nozzle may include one or more apertures to permit fluid flow therethrough. The filler valve 1226 may move along a longitudinal axis of the nozzle 1230 to open and close the fluid flow path through the nozzle. The filler valve 1226 may be contoured, including a rim to mate with the bottom section 1222 of the container connection device 1202. This connection permits the dispenser connection device 1204 and container connection device 1202 to move together during the coupling/decoupling to reduce leaks. Magnet 1228 may be a neodymium magnetic ring coupled to the filler valve 1226, which is designed to attract magnets 1220 of the bottom section 1222 of the container connection device 1202, and further ensures that the container connection device 1202 moves with the dispenser connection device 1204 during use. The magnetic attraction may further stabilize container 1206 during the filling process. The collar 1232 couples the filler valve 1226 to the nozzle 1230, permitting the filler valve 1226 to translate along the nozzle while remaining coupled to the nozzle during use. The collar 1232 may be formed from a flexible rubber material that is shaped to easily compress, but which expands back to its pre-compressed shape to provide a bias for the filler valve 1226 to close nozzle 1230. The collar 1232 may further provide protection against leaks during use.

In one embodiment, the dispenser may further include other features such as a basin, drain, lights, etc. For example, the dispenser may include a housing 1234 for switches, lights, or other features. The housing may be used as an advertising or identification space, such as to identify the type or brand of beverage coupled to the dispenser. Housing 1234 may include LED lights that illuminate the liquid during the filling process. Pressure switches may be incorporated in the housing to trigger the LED lights or may be used to activate the filling process when a container is detected on the housing. The LED lights may alternatively or also be housed around the basin or other parts of the dispenser connection device. The dispenser may also include a basin 1236 to catch any overflow during the filling process. The basin 1236 may be used to intentionally overflow a foaming beverage in order to remove excess foam from the top thereof. The basin 1236 may include a drain 1238 to permit easy clean up after use. The dispenser may include conduit 1240 to couple the dispenser to a fluid source. The conduit may be a manifold permitting attachment to multiple fluid sources, thereby permitting the dispenser to be used for multiple beverages. In such an embodiment, the desired beverage may be chosen by the user via a switch or rotation of a manifold selection member.

Any of the above described embodiments of the dispensing system and combinations thereof may further include a flushing device to remove liquid from the dispensing system between uses. FIGS. 13-14 illustrate representative flushing devices according to embodiments of the invention. A fluid conduit may be coupled to the dispenser directly or indirectly, such as through a manifold. A valve may be coupled between the fluid conduit and the nozzle. A water or flushing line may also be coupled to the dispenser through a separate valve. The flushing line may alternatively be coupled to the manifold as one of the liquid sources coupled to the dispenser. Once the liquid of choice, such as beer, is poured, the valve coupling the beer line and the container is closed. The valve coupling the dispenser and the flushing line is then opened to flush the dispenser and connections. A drain may be included to drain the flushing fluid (e.g., water) from the connections. A new container may then be connected and filled without being comingled with the previous liquid choice. Preferably, water may be used to flush the dispenser and coupling devices. However, other substances may be used, such as, cleaning agents, solutions, alcohol, or forced air, to remove the previous contents from the coupling devices.

FIG. 13 illustrates a representative flushing device 1300 according to embodiments of the invention. The dispenser may include a nozzle 1302 as previously described and may be connected to a liquid conduit 1304, such as a beer line. The dispenser may also include a valve 1306 between the liquid conduit 1304 and the nozzle 1302 to start and stop the flow of the desired liquid. A flow meter 1308 may also be coupled to the liquid conduit 1304. Once a container is connected to the dispenser, the valve 1306 may be opened, permitting the desired liquid to flow from the liquid conduit 1304 into the container, through the nozzle 1302. The valve 1306 may be closed to stop the flow of fluid, when the container is full. A flushing line 1308 may also be coupled to the dispenser which connects the nozzle 1302 to a flushing source, such as water. A flushing valve 1310 may be included between the flushing line 1308 and the nozzle to permit the flushing fluid to clean the nozzle 1302 after the filling process. The valve 1306 and flushing valve 1310 may be manually or automatically operated. In one embodiment, the valve 1306 and the flushing valve 1310 are electromagnetic valves that include a steel ball held out of the fluid flow path when the valve is opened by an electromagnet. The steel ball is then permitted to obstruct the flow path when the valve is closed.

A drain valve 1312 may be used in conjunction with the flushing valve to drain the flushing fluid from the dispenser. In one embodiment, activating the flushing valve 1310, which permits flushing fluid to flow through the dispenser, also activates a drain valve 1312. Therefore, the drain valve 1312 may provide an alternate path for the flushing fluid after rinsing the nozzle 1302, so that flushing fluid does not exit from the dispenser. Alternatively, the flushing fluid may be permitted to exit the dispenser through the nozzle, as the chosen liquid would with the container in place. In this embodiment, the dispenser may include a basin and drain to catch and dispose of the flushing fluid after rinsing.

In one embodiment, the method to flush the dispenser after use may include: (1) coupling a container to the dispenser; (2) opening a valve to permit fluid to flow between a liquid conduit and the container; (3) closing a valve to stop fluid flow between the liquid conduit and the container; (4) removing the container from the dispenser; (5) opening a second valve to the flushing line; (6) flushing the dispenser; and (7) closing the second valve to the flushing line.

FIGS. 14A-B illustrates one embodiment of a flushing device 1400 to remove liquid from the dispensing system after use. In this embodiment, the liquid to the dispenser is removed from the dispenser connection device without a flushing fluid, reducing the likelihood that the liquid will become warm and stale at the dispensing location. By removing the liquid from the dispenser, it may be refrigerated along a conduit or below the dispensing location. Operation of the flushing device 1400 is described below.

First, a container (not shown), is placed on a dispenser 1402, which activates a pressure switch. The pressure switch opens a first valve 1404. A second valve 1412 is then opened to create a fluid flow path from the liquid conduit 1418 to the container. The second valve 1412 may be opened by an operator manually activating the valve by using a switch. During filling, a first collar 1406 and a second collar 1408 remain closed. A spring 1410, such as a rubber band, may be used to bias the collars in a closed position. The second valve 1412 may then be manually or automatically closed to shut off the fluid flow to the container. The container may then be removed from the dispenser 1402, deactivating the pressure switch. The pressure switch then turns the first valve 1404 off and simultaneously turns the second valve 1412 on, so the liquid line is still closed to the dispenser. However, liquid may reach the second collar 1408 and fill with fluid from the fluid line 1418 causing it to expand. The expanding second collar 1408 causes the first collar 1406 to draw the liquid from the dispenser down into the first collar 1406, while closing the seal 1414. The seal 1414 may prevent contaminants from entering the dispensing system while a container is not being filled. A guide rod 1416 may be used to permit the first and second collar to translate between an expanded and collapsed position appropriately.

FIG. 15 illustrates an exemplary dispensing system including various embodiments as described herein, including the flushing device. FIG. 15 illustrates a representative dispensing system including features as described an illustrated in FIGS. 4A-B and FIG. 6. Features with like numbers represent similar components as described above. The a container connection device includes a upper section 402 and lower section 404 threaded together through container 406. Seals 422 and 420, such as o-rings may be used to create a liquid tight seal between the container 406 and the container connection device. A cap 430 may create a valve for the container connection device. Seals 436, 438, 440, such as rubber gaskets, may be used to create liquid tight connections between the cap 430 and upper section 402, and the lower section 404 with the dispenser platform 606. Magnetic rings 432 and 424 bias the cap 430 closed, while magnetic rings 426 and 608 couple the container connection device to the dispenser connection device. Nozzle 602 pushes against cap 430 to overcome the magnetic attraction and open the valve of the container connection device. The magnets 432 and 424 attract one another, even while the nozzle 602 is pushing the cap 430 open, the attraction retaining the cap 430 on the tip of the nozzle 602 during filling. Contouring of the cap 430 and nozzle 602 may assist in properly retaining the cap relative to the container connection device during the filling process.

In one embodiment, a tether, coil, spring or other device may be used to ensure the cap remains aligned with the bottom of the container and properly closes after the nozzle is removed. The cap may be made of a generally magnetic material, incorporate magnetic material, or may include a separate magnetic ring, or magnetic pieces to create the downward force. The corresponding magnet may be located inside or outside of the pitcher, as long as it draws the cap closed. Other embodiments may use other forces to close the cap, such as gravity or screwing.

In one embodiment, another pair of magnets may be used between the container and the dispenser. The container may use a separate magnet to attract the dispenser or it may use the same magnet used to attract the cap. These magnets may be used to stabilize the container while it is being filled. Other embodiments may use other forces to stabilize the pitcher, such as screwing or a mated fit between pitcher and base.

In one embodiment, the dispensing system may include decorative devices. For example LED lights 1502 may be included in housing 1504 and may flash or light up in various patterns depending on what liquid is selected, what container 406 is connected (e.g., pitcher or glass), whether the container is properly connected, etc. Also using light under the filling beverage to illuminate it may make the beverage look more appealing or appetizing. For example, an amber light under a darker beer may change the appearance thereof to appeal to a wider consumer base. Changing the tint of the light, or the color completely for different beers or certain drinks can be achieved. The light or lights may turn on when the pitcher is being filled, and may turn off when the pitcher is removed from the dispenser through various electrical, mechanical, or magnetic means. Alternatively, the lights could be modified to project images, messages or advertising on the container. The container 406 may also increase customer attention by rotating or moving as it fills. Housing 1504 may also include switches 1506 to control the dispenser or lights.

In one embodiment, the dispenser may be coupled to a fluid source. The dispenser may be coupled to one or more fluid sources through a manifold 1508 in order to couple multiple liquids to the same dispenser. A switch may be used to choose the desired liquid.

In one embodiment, a flushing device may be coupled to the dispenser. For example, a flushing line 1510 may be used to rinse the connections between uses. This may permit various beverages to be connected to the same dispenser and reduce or prevent unintentional contamination or intermixing of beverages. This may also prevent the beverage from sitting in connection lines and becoming warm or stale as discussed above. A drain valve 1512 may be include to provide an alternate path for the flushing fluid after rinsing. Drain lines 1514 may be coupled to the drain valve 1514 and the basin 1516 to remove any overflow fluid during filling or flushing fluid after cleaning.

In one embodiment, a lever in the appearance of a beer tap handle may be used as a switch to start and stop the filling of a container from the dispensing system. Alternative embodiments include other devices besides a tap handle to initiate the pour, including pushing a button to open a valve, turning a knob, or other devices known to start the flow of a pressurized liquid. The initiation of fluid flow may also be automatic by use of a pressure switch or by opening the fluid flow path through the connection of the container connection device with the dispenser connection device. A timer may alternatively be activated to fill the container depending on a programmed container size, such as a pint or pitcher. Other automatic devices, such as pressure switches may also be used to automatically turn off the fluid flow when the container is filled. Utilizing embodiments of the device and assembly may make tap handles purely aesthetic. The flow may be controlled by an electronic switch or other device. Therefore, the tap handles can be arranged any way based on aesthetics, utility, or personal preference.

Embodiments of the present system may be used to create layered shots of alcohol. By dispensing through the bottom of a glass, all one has to do is arrange the parts in the order they would like them to be in, filling the shot glass first from the bottom with the part that will be on the top. The assembly may be adjusted to reduce the flow through the filling device, depending on the application. Therefore, if the filler is used for shots of alcohol, the flow may be reduced to permit the liquor to seep into the shot glass. However, the flow may be increased if the device is used for beer, soda, or other beverages. The nozzle may also be designed with one or more apertures with associated dedicated conduits at various heights to permit filling by multiple liquids at the same time. For example, this embodiment may be used for layered beers such as a black and tan, or may be used with flavored sodas such as cherry coke.

A container connection device as disclosed herein may also be used with a removal system to drain the contents of a container after it has been filled by a dispenser. The removal system may be used, for example, as a “beer bong” to rapidly drain the contents from the container. The removal system may be coupled to the container connection device to rapidly remove the contents through a bottom of the container. For example, FIGS. 16A-B illustrate an exemplary embodiment of a removal system used with a container connection device as described herein.

FIGS. 16A-B illustrates an exemplary removal system 1600 used to dispense a beverage from a container 1602 through a bottom 1604 of the container. Generally, a rapid drain attachment 1616 may be coupled to a container 1602 to drain the contents through its bottom 1604. A conduit 1606 may be coupled to the rapid drain attachment 1616, and may be used to transfer the liquid from the container 1602 to a desired location. The coupling end of the rapid drain attachment 1616 may include a platform 1608 that aligns and interacts with a valve in the bottom of the container 1602. The interaction between the platform 1608 and the valve may permit fluid flow during removal, and may provide a seal between the rapid drain attachment 1616 and the container 1602 when connected. The valve may be a cap 1610 covering a hole or opening in the bottom of the container 1602. The cap 1610 may be normally biased close to prevent the liquid from exiting the container 1602. The rapid drain attachment 1616 and cap 1610 may interact when coupled to permit liquid to flow between the container 1602 and conduit 1606.

In one embodiment, the cap 1610 may include a magnetic material or ferrous metal. To bias the cap normally closed, the bottom 1604 of container 1602 may include a ring 1612 that may include a magnetic material or ferrous metal that attracts the magnetic material in the cap 1610. A sealing feature (not shown), such as a gasket, may be used to ensure a liquid tight seal when the cap 1610 is seated in place under the influence of the ring 1612.

The rapid drain attachment 1616 may interact with cap 1610 to dispense the beverage from the container 1602. Rapid drain attachment 1616 may include a conduit 1606 to transport a liquid from the container 1602 to a desired location. The conduit 1606 may include a flexible portion 1614 to permit easy configuration of the fluid flow path to the desired location. The conduit 1606 may interact with the platform 1608 of the removal system 1600 in order to fill the container 1602. When the rapid drain attachment 1616 is coupled to the container 1602, fingers 1618 may be used to raise the cap 1610 of the container 1602, permitting liquid to flow between the container 1602 to the conduit 1606. In one embodiment, the rapid drain attachment 1616 may include a platform 1608 to seal the connection between the rapid drain attachment 1616 and the container 1602. The platform 1608 may include a ring 1620 that includes a magnetic material or ferrous metal to secure the ring 1612 of the container 1602, and thereby securing the connection of the rapid drain attachment 1616 to the container 1602 during content removal. Platform 1608 may additionally include a seal, such as a gasket, to reduce leaking between the rapid drain attachment 1616 and the container 1602.

The rapid drain attachment 1616 may be used after filling the container 1602, as described below. The container may be disconnected from the beverage dispenser and coupled to the rapid drain attachment 1616. In use, when the rapid drain attachment 1616 is coupled to the container 1602, fingers 1618 may push open cap 1610 of container. The rapid drain attachment 1616 may then be used to rapidly remove the container 1602 contents from a bottom 1604 of the container 1602, and potentially through a conduit 1606, which may further include a flexible portion 1614. As an example, the rapid drain attachment may be used with the beverage container, such as a pitcher, to create a “beer bong.” Rapid drain attachment 1616 may further include an opening mechanism to trigger the fingers 1618 to open valve in the container 1602 and permit fluid flow out of the bottom 1604 of container 1602. The rapid drain attachment 1616 may alternatively or additionally include a valve at an outlet to stop the flow out of conduit 1606.

While some specific embodiments have been described herein, the invention is not to be limited to these embodiments. The invention is to be understood as not limited by the specific embodiments described herein, but only by scope of the appended claims. Features and details from one or more described embodiments may also be combined, added, or removed to form other embodiments within the scope of the invention, as the described embodiments are merely exemplary of various features considered novel and within the scope of the invention. Embodiments of the invention may be used where a constant seal between a container and the source of a non-solid (e.g., fluid or liquid) material needs to be maintained. Embodiments of the invention may permit the container to be repeatedly coupled to (without breaching the seal of the container) and then removed from the source.

Although embodiments of the invention are described and illustrated herein in terms of liquid, beverage, or beer dispensers, it should be understood that embodiments of this invention are not so limited, but are additionally applicable with other liquids and substances. In the embodiments implementing magnetic materials, the dispensers are preferably used with substances that would not interfere with the magnetic interaction of one or more components (e.g., non-ferrous substances). Furthermore, although embodiments of the invention may be described and illustrated herein in terms of filling a container from its bottom, it should be understood that embodiments of the invention are also applicable to filling from a bottom portion of the container. The term “bottom” should generally be understood to include any lower portion of the container such that entry of the filling liquid is generally from under the surface of the liquid in the container for at least a later part of the filling processes. For example, the ‘bottom” may include a side of the container where initially the filling process will be above the surface of the liquid in the container, but if the container is filled to capacity, the filling process will be under the surface of the container liquid for a later part of the filling process. Embodiments of the invention may also be used for filling a closed container from a top portion thereof.

Although embodiments of this invention have been fully described with reference to the accompanying drawings, it is to be noted that various changes and modifications will become apparent to those skilled in the art. Such changes and modifications are to be understood as being included within the scope of embodiments of this invention as defined by the appended claims. For example, specific examples are provided for shapes and materials; however, embodiments include those variations obvious to a person skilled in the art, such as changing a shape or combining materials together. For example, specific examples include a magnetic material or ferrous metal included in a ring in either the container or beverage dispenser, but the embodiment is not so limited, and may include a magnetic material combined in the container or dispenser, such as by using blocks, pellets, or other variations. Further, embodiments disclosed herein generally describe a beverage dispenser for creating a fluid flow path and a separate valve to creating the fluid flow, however, these features may be combined into a single device.
